"I'm hoping Netrunner (which is one of the best CCGs ever made) brings more attention to LCGs from dedicated CCG players."
Maybe, but it's not going to be easy. The more someone has invested in a lifestyle game:
1. The less money they have to try out other games
2. The harder it is to overcome their resistance to try something else
#2 is especially important I've noticed. I'm mainly going by tabletop minis games experience here, but there's a very strong tendency in some people to cling to their existing game they've spent a lot of money on even if better games exist. In their mind, playing and enjoying another game is effectively admitting that they wasted all that money on their current game (yes, I know it's a stupid way to think but it exists) and some people can't deal with that.
If Shadowfist and Magewars succeed over time, we may see other games follow, and if multiple companies are following an LCG-like model that will lend legitimacy to the idea that will help convince more people. Note that I say "succeed over time" because one of the important characteristics of these games it that the company gives a long term commitment to keep supporting the game and to continue doing a good job with balance and correcting any flaws that arise. If the players don't trust them to do that then they're not going to want to invest. So for instance, Magewars is doing well now but they haven't really been tested as to their ongoing support yet.
